This invention relates to a slug ejector. It is designed for use inconnection with a coin or token operated or controlled device. It hasfor its general object to eject coins or tokens which are not of theproper size, shape or weight or are otherwise of an unsuitable tersthroughout the specification and drawit is a plate provided on one sidewith an inclined flange A wh ch may be notched as at A A The plate haspreferably formed integrally with it a generally curved enlargement orthickened part A In the form here shown this part conforms generally tothe outline of a coin vending machine with which the slug ejector isassociated. That portion of the slug ejector lying generally below theflange A is within the body of the machine and that portion of the slugejector lying generally above the flange A is outside of the machine ornormally projects upwardly from it. The plate A is provided with alaterally extending overhanging flange A A is an opening formed in theplate A. A is a. magnet removably held in position by means of the screwA and the washer A A is a boss formed on the plate A and adapted to havepositioned upon it a bearing supporting plate A which is pivotallymounted as at A and is provided with a slot A in its larger end. A is ascrew extending through the slot A and positioned in the plate A, bymeans of which the bearing supporting plate A may be moved and supportedin adjusted position. A is a curved slot in the plate A through which ahearing or pin A projects into the interior of the slug ejector.

An irregularly shaped passage is formed within the plate A. It consistsof the portion B which in one form of the invention is directedgenerally down so that it adjoins an inclined strai ht portion B whichjoins it at an angle. t its lower end the portion B which communicateswith a curved port-ion B which finally communicates with an enlargedspace or passage 13 which is open at its bottom as at B. Formed in thesides of the passage are a plurality of grooves or eX- tendeddepresSionsB B They are separated by a land or raised portion B whichextends with them throughout the length of the passages B and B C is acoin controlling lever balanced on the bearing A and lying within theenlarged space 13 It is provided at its lowerend with a weighted portionG and at its upper end with a curved coin contacting arm 0 D is a platesomewhat similar to the plate A. It is provided with a flange D and hasin its inner face grooves D corresponding to the grooves B, B in theplate A and positioned oppositely to them when the parts are assembledas shown in Figure 2. The grooves D are separated by a raised portion orland D which corresponds to the similarly raised portion or land Bformed in the inner face of the plate A. At its bottom adj a cent theopening 13*, the plate l) is provided with a laterally inclined flange Dand it has secured to it a slug guiding member D which is provided withan inclined portion D and guiding and limiting wings D It is fastened tothe plate D by means of screws D E is a plate positioned upward of theplates B and D where they oin and it overlies both of them. It isprovided with a slot E to permit the introduction of a coin or token anuis removably held in position by screws, E

It will be obvious that while I have shown and described an operativedevice, many changes may be made in the size, shape, number, relationand distribution of parts without departing from the spirit of myinvention, and I wish therefore, that my descrip tion and showing beconsidered as in a large measure diagrammatic.

The use and operation of this invention are as follows:

When a coin or token of the proper size, shape and weight is inserted inthe slot IE it 5 moves more or less vertically downwardly through theshort, generally vertical disposed passage B. It then strikes the flatinclined bottom of the passage B and rolls along this:

reversel y curved passage 13 Normally it flies; clear across thispassage and strikes. the righthand orouter wall of the passage B Itsrotation is then reversed and it rolls down the curved bottom of thepassage B past the slot A and the magnet A. It umps off the end ofthecurved bottom part of the passage B emerges into the enlarged chamber Band strikes the upper portion C or the lever 5 G. Since its weight, sizeand shape are proper, it will strike with suflicient force tooverbalance the lever. It will raise the weighted end C of the leversufliciently to permit it to fall off the left of the upper end C Itthen passes outward through the opening B and into the coin controlledor coin operated mechanism with which the slug-ejector is associated.These parts are not here shown as they form no particular part of thepresent invention since the slug ejector may be as sociated with avariety of other mechanisms. If the coin is not of the right size orshape orweight, if for example, it is of a metal responsive to themagnet or if it is too light, it will notmove with suiiicient force toclear the space between the end of the bottom of the curved passage Band the lever C It will not pass on into the mechanism but will beejected through the slug ejector.v Even if it does reach this part ofthe machine with such force to clear the space and to strike the memberC if it does not strike this member with a force sufficient to rotate itso as to permit the coin to be discharged to the left over the end C ofthe lever, it Will nevertheless fall backward into the passage X and bedischarged out of the machine through the slug ejecting passage X andthe chute D VVhere' in the specification and claims I have used the wordcoin or token, I do not wish to be limited to either of these. It istherefore understood that where the device is applied to a coin operatedor coin controlled mechanism, normally the coin or some special form ofslug or token will be used. It is the purpose of the method andapparatus of this machine to eject coins and tokens or slugs which arenot of the proper size, shape and weight. The mechanism is adjustableand when adjusted normally, it is arranged to operate with a particularsize and shape of coin, slug or token. It is therefore arranged toreject others which do not come up to the standards set up at the timethe machine is adjusted. I The invention, however, is not particularlylimited to this feature and may be used for the classification of otherobjects whether or not it is associated with a coin operated mechanism.

I claim:

1. In a token classifienan inclosure defining a tortuous passageterminating in substantially a horizontal position and a chamber towhich said passage leads, a movably mounted element within said chamber,said passage so shaped that a token deposited within it moves through itunder the infinence of gravity alone, is projected generally laterallyacross the chamber under the influence of its momentum solely andagainst the movable element, said movable element so mounted and; beingof such weight that a coin striking it with more than a given force Iwill move it sufliciently to pass beyond it and a coin striking it withless than a given force will fail to pass beyond it.

2. In a token classifier, means for classitying the tokens accordingtoweight, including an inclosure defining a tortuous passage into whichthe. token may be introduced and along which it is adapted to move, thepassage so shaped as to compel the token as it rolls to move through itunder the force of gravity alone and to cause the token to rotate firstin one, direction and then in another duringits passage, means forsubjecting the token to a magnetic influence as, it moves through thepassage, and means for projectwith the passage a chamber within which islocated a movable element against which the token is projected, saidelement adapted to be moved more or less by the token as it iscontacted,'the degree of, such movement depending upon the force withwhich it is struck and affecting the classification of the token. I I

3. In a token classifier, an enclosure defining reversely directedsubstantially horizontal passages, a chamber to which one of saidpassages leads, a movable member mounted in said chamber and spaced fromthe one end of one of the substantially horizontal passages, saidpassages and movable member being so positioned that a coin traversingsaid chutes will contact said movable member under the influence of itsmomentum with such forceas to pass over said member or fail to pass thesame.
